Cant tame monsters

So to tame monsters you need to first have space in your monster barns. Then you give them an item and should see a heart icon above them. It'll flicker and if it changes to a skull icon you have to try again. Different monsters have items they favor but pretty much anything will work. I usually just use whatever grass I have on hand. Only boss monsters require specific items for taming.
Now your spell seal has two different purposes. If you wrap the monster in chains, this allows you to possibly steal an item from them. If you fully charge your spell seal (like you would for wanted monsters) then this allows you to temporarily tame them for a day.

kittykat0510 pretty much covered the way you can tame monsters. Few things can be used to increase the odds of success:
A higher taming skill helps: you raise it by taming monsters (obviously) but also by brushing and giving gifts to your tamed monsters.
Brushing a monster before attempting to tame it. You can brush (if I remember correctly) up to 10 times.
Hitting a monster with a weapon that has the love attribute (again up to 10 hits). In that case you want a low level weapon or even better a weapon upgraded with a Scrap Metal+ as it will only inflit 1 damage and shouldn't kill that monster.
You can give up to 10 gifts to a monster in order to tame it. If the 10th attempt fails, you'll have to try with another one.
You've given bonus if you have monsters of the same species in your barn (for example having tamed a Hornet make it easier to tame a Queen Bee).
Being of a higher level than the monster helps. The opposite drastically reduces the chance of success.
Boss monsters, no matter what you do, are capped to a maximum of 10 or 15%.

Finally in RF4 if you had a specific monster in your barn it was harder to tame another one of the same subspecies and the more you had, the lower the odds. I can't say if that's still true for RF5.
