Hide date, post name, category and social icons on posts

I want to permanently be able to hide the post name on one (or if i can’t hide it only on one, then hide it on all) of my posts. It results in wasted space and sometimes makes it look like a blog where I don’t want it to.

I do not want the blog categories to show either….again trying to get away from the blog look.

I also need to remove the date of the post permanently on all posts.

I need to TEMPORARILY be able to remove ALL Social Media Icons until I have time to set them up. I tried changing this in the Theme Setup in the Footer section…but they are still showing on Posts.

I need to add Custom CSS to make these changes.

Your help is appreciated.
