Can i update mac osx 10.7.5 to 10.10...?

Only if you’ve previously gotten Yosemite from the Mac App Store and your computer meets the system requirements for it. If you haven’t, you’ll need to upgrade to El Capitan or Sierra, or can’t upgrade, depending on what Mac model you have.

That depends on what Mac you have and its sub-model.

Some older ones are constrained to running no higher that OS 10.7 so, lacking any information from you about your equipment we cannot help without more from you. You can find you model and submodel by selecting the Apple menu at the left end of your menubar. First item under that menu is "About this Mac." The result window will look something like this:

Somewhere in the window will be the model name ("iMac" in the example") and the all-important sub-model ("21.5-inch Mid 2011" in the example). Please tell us what you computer shows for those. Then we can a) give you a relevant answer, and b) get you moved to the proper forum for that Mac model where you will get more activity.
