Please tell me the usage of shall,should, will, would and could etc.
Shall and Will are modal verbs primarily used to express the future.
In general or colloquial usage, will is used for all pesons, both sg. and pl. Shall is much less commonly used, but is often used in first-person offers and occasionally for emphasis.
I shall/will see.
You will see.
He will(shall) see.
We shall/will see.
You will see.
They will see.
As the past of will, for example in indirect speech.
"The next meeting will be in a month's time" becomes
''He said the next meeting would be in a month's time''.
Polite requests and offers (a 'softer' form of will)
Would you like another cup of tea?
Would you give me a ring after lunch?
I'd(I would) like the roast duck, please.
In conditionals, to indicate 'distance from reality': imagined, unreal, impossible situations
If I ruled the world, every day would be the first day of Spring.
It would have been better if you'd word processed your assignment.
After 'wish', to show regret or irritation over someone (or something's) refusal or insistence on doing something (present or future)

(This is a complicated area! Check in a good grammar book for full details!)
Talking about past habits (similiar meaning to used to)

Future in the past

Can & Could usage:
Talking about ability

Can you give me a ring at about 10?
Could you speak up a bit please? (slightly more formal, polite or 'softer')
Can I ask you a question?
Could I ask you a personal question? (more formal, polite or indirect)
Could is used as the past of can.

Choice and opportunities
If you want some help with your writing, you can come to classes, or you can get some 1:1 help.

Could (NOT can) is sometimes used in the same way as might or may, often indicating something less definite.

Obligation: weak form of must

Things which didn't or may/may not have happened

You shouldn't have spent so much time on that first question.
Ought to usually has the same meaning as should, particularly in affirmative statements in the present:
You should/ought to get your hair cut.
Should is much more common (and easier to say!), so if you're not sure, use should.
I am sorry, it is a bit long... :D
