their meanings will change acording to situations and also one must use proper words according to the situation.

"I should have told you." 'told' is past tense therefore 'should have' is appropriate.
"I should tell you." 'tell' is present tense therefore 'should' is present tense.
"I shall tell you." Again 'tell' is present tense.
'Could' 'would'
Rules similar to those for choosing between 'shall' and 'will' have long been advanced for 'should' and 'would', but again the rules have had little effect on usage. In most constructions, 'would' is the auxiliary chosen regardless of the person of the subject:
(If our allies 'would' support the move, we 'would' abandon any claim to sovereignty. You 'would' be surprised at the complexity of the directions.)
Because the main function of 'should' in modern American English is to express duty, necessity, etc. (You 'should' get your flu shot before winter comes), its use for other purposes, as to form a subjunctive, can produce ambiguity, at least initially: (I 'should' get my flu shot if I were you.)
Furthermore, 'should' seems an affectation to many Americans when used in certain constructions quite common in British English: [Had I been informed, I 'should' (American 'would') have called immediately. I 'should' (American 'would') really prefer a different arrangement.]
As with 'shall' and 'will', most educated native speakers of American English do not follow the textbook rule in making a choice between should and would.

I should have told you:this is present perfect
I should tell you:present simple
I shall tell you:past simple

This is gramatical question. You should refer a English Grammar Book which will clear your doubt.
