It´s pretty hard to translate Turkish verbs like that into English as the latter doesn´t really have the exact equivalents due to its nature. Try this site it´s good for checking conjugations and it may help you to make out what different forms of Olmak mean.
The trouble with the forms you ask about is that some of them are just verbs in different tenses (eg olmadi = wasn´t) while others are gerunds used in a particular case and ending (eg olmadiðini = your not being /used as object of a sentence). Additionally, you are asking for translations of an auxiliary verb used not only to convey meaning but quite often performing a grammatical function (thus unable to be translated without context)
The bottom line is, don´t try word-for-word translations, but rather focus on one grammatical aspect at a time and soon you´ll get there 
I have tried a few myself some i know and some im not sure of.
Olmani - To Be< not too sure (your being used as an object in a sentence)
Olman - To Be< not too sure (your being)
Olmuþ - Been
Olmadi - Not (wasn´t)
Olmak - Happen/Become/Be
Olmadan - Without
Olmadik - Lying (ahmm...we weren´t?)
Olmadiðini - Whether (I don´t think so...however I can´t translate it, I think the closest would be "that you aren´t")
Olmas - ??? (olmaz?)
Olmasi - ??? (his/her/its being (again used as an object in a sentence))
Olmamak - Not to be/Not happen
Isterdim - I would Like
Istemezdim - I wouldn´t like
Isterim - I want/I would like
Istiyorum - I want
Istediðin - You would like/Would want (~the one you want/that you want)
Istiyorsun - Do you want?
Istemiyorum - I dont want
Istemediðini - You dont want (~your not wanting)
Istersin - Do you want?
Is it ok to say Istemiyorsun - You dont want!????
Also could someone tell me what Iðtiyacim Var Yanimda Olmani Istiyorum Bana Sarlimak Gulmeni isterim Lutfen. Means!!??
I think its something like. I need you to be here beside me, I want you to hug me no idea what gülmeni means. Gülmeni =your smiling (gerund from the verb gülmek used as object in the sentence)
Any help would be great.
