Answers to your questions (note hyperlinks):
1. Short answer is yes.
2. Correct.
3. Partially yes, with some reservations.
Right now it takes a special type of low-draft (about 8m fully loaded) container ship to berth at Chittagong port given its low draft jetties (around 10m draft). These are known in the trade as 'Chittagong Max' vessels or also known as the popular Zhejiang 2700 design (for 2700 TEU capacity and about...). Maersk and other shipping line order these vessels for most Bay of Bengal ports like CTG and Yangon (Sittwe) because draft is low around these ports. Here is Maersk ship 'MCC Chittagong', a vessel of this class. This one carries containers back and forth between Singapore/Port Klang and Chittagong, sort of doing semi-lighterage duties.

These are roughly 37157 DWT displacement ships.
However large container-carrier vessels with normal draft requirements routinely exceed 10m draft call at transshipment ports like Singapore and Colombo. They cannot come to Chittagong so garments and other exporters have to incur extra shipping charge.
Supramax is the largest of the vessels with a size of around 50,000 to 60,000 DWT and can be as long as 200 meters or 656 feet. These are high draft vessels so about 20+meters draft. These have to anchor in outer anchorage or Kutubdia island south of CTG port. If we build the deep-water port at Sonadia or Kutubdia, those ports will be able to accommodate these classes of ships.
Handymax vessels are slightly smaller and have a displacement of 40,000 to 50,000 DWT. These ships are usually at least 150 meters or 492 feet. These are the bulker vessels that are being discussed in this thread and won't normally be able to berth directly in CTG if they are of normal high-draft design (draft about 12 to 15m). However these new builds in China will probably be built to low-draft design (under 8m) and will be able to berth in Chittagong.
Handysize are even smaller-sized ships with a capacity ranging between 15,000 and 35,000 DWT. These vessels are ideal for small as well as large ports, and so make up the majority of ocean cargo vessels in the world. These are OK to berth in Chittagong port jetties directly if they are under 20,000 DWT (around 8~9m draft).
See images below for guidelines for drafts for various TEU classes.
In the neighborhood, Chennai and Visakhapatnam ports have natural deep-draft ports and harbors so they can accommodate much larger container vessels, thereby lowering shipping costs for their users.

thanks for the detailed answer..... but probably I was unable to explain my questions to you.... let me explain a bit further....
1. if we get a deep-sea port, would that mean that most of the ships that come to Bangladesh would directly download on a jetty? - I was referring to "ships", not just "container ships".... would this mean that big ships would download their cargo on a jetty and then we would re-load the cargo on another smaller "lighter" ship to carry the cargo to the rest of the country? or do we load the cargo on a truck rather than a "lighter" ship?.....we're talking about a minimum of 70 million tons of goods....
2. we would no longer require to send ships to Colombo or Klang or Singapore to fetch our containers left there by bigger ships? - so we scrap our own ships, or do we start our own container shipping lines to challenge Maersk and others globally?
3. so, we can rely more on our own ships to ship our goods rather than spending $6bn+ on shipping per year, thereby putting huge pressure on foreign reserves? - related to the second question.... so, our ships take only our containers to Europe?...... how big are we thinking this ship to be?..... the same ships would go to China to bring imported goods containers?..... how many container ships do we require?.... do we let international shipping lines to still operate from our ports or do we buy or build an international container shipping line that would challenge Maersk and others?
