Many of the old tiles on my bathroom floor are simply coming loose. See the attached photo. The land-lord is not prepared to replace them with new ones and I can't afford to do that myself, so I am looking for a relatively simple/newbie way to re-attach them to the concrete that lays beneath.
In plain English, I need to know what glue/adhesives/products to use, what steps to take and any mistakes I should avoid.

Those tiles did not adhere properly for one or more of several reasons: inadequate substrate preparation, inadequate or improper adhesive, adhesive not used correctly, etc.
My opinion is: not enough adhesive was used to bond the tiles. Also, the concrete may not have been made completely smooth and clean prior to installation.
There are two basic ways to bond that tile to concrete, the most common method is thin-set mortar (a cementitious tile adhesive), the second would be a pre-mixed tile adhesive sometimes called mastic.
