I live in San Diego and we are gonna plant some sunflowers but the only space available gets like 5 hours of direct sunlight. It is in a wide alley, and surrounded by wide and very light colored buildings. Do you think that will be ok?

I’m guessing with your climate that would be ok. They might get a little scraggly but they should grow adequately. The reflection from the walls should help.

So, yours might be a little stunted, but should be OK.
Mine grow wild due to the vigorous plantings on my squirrels and chipmunks. I reside in Wisconsin. Even on the north side of my property, they get to full size during summer.
I’d say yours should be fine in the alley.
‘Full sun’ usually means a solid 8 hours or so, but, they should do well enough.
You can also rotate some plantings, plant some now, more in June, July for staggered bloomings. I used to live in San Diego and the growing season, especially more inland, the ‘Cajon zone; etc. will afford you a looong growing season.
OMG! I had an apartment in El Cajon about 20 miles inland..October was like 110 degrees! Gah!
