when i got my phone i imported some contacts from the sim card and others from my gmail account. some contacts i entered manually. why do only some of the contacts syncronize with icloud
Welcome to the Apple Community.
Check that all your contacts are in your primary iCloud group, only contacts in this group will sync with your primary iCloud account.
In the example above I have a secondary iCloud account, but you might also see a 'On My Phone' group.
Would you be kind enough to elaborate your answer in terms a novice like me can understand. I am having similar problems, and further problems in getting my Office 2010 contact list to the iCloud and to my Mac Air, iPad and iPhone.
