Placement rules (RID) and the real-world uses of reflexives
All these pronouns follow two placement options: 1) place them before a conjugated verb or negative command; 2) attach them to an infinitive (-ar, -er, -ir), a gerund (-ando/-iendo), or a positive command. The order when combining is always RID (Reflexive → Indirect → Direct).
Direct pronouns are very common and easy to use. Most verbs act on things, and since things are often third person, you will frequently see lo, la, los, las. Remember that Spanish nouns have gender and number, so the pronoun must agree. However, the other direct pronouns (me, te, nos, os) are also important.
Mi madre me llama todos los días.
My mother calls me every day.
¿Te invitaron a la fiesta?
Did they invite you to the party?
¿El libro? Sí, lo tengo.
The book? Yes, I have it.
¿Las llaves? No, no las encuentro.
The keys? No, I can't find them.
El profesor nos saluda.

¿Os esperan en la entrada?
Are they waiting for you all at the entrance?
Los vi en el garaje.
I saw them in the garage.
Voy a comprarlo / Estoy comprandolo / Cómpralo.
I'm going to buy it / I'm buying it / Buy it.
Indirect pronouns are triggered by verbs that can involve giving or communicating something to someone. Typical categories: saying (decir, contar, susurrar, gritar, informar, explicar, preguntar) and giving (dar, enviar, escribir, lanzar/tirar, regalar, ofrecer, traer, mandar). Always check: can you say/give something to someone? If yes, an indirect is possible.
¿Me prestas tu carro?
Will you lend me your car? (to me)
Te envié un mensaje.
I sent you a message. (to you)
Le doy el libro a Ana.

El profesor nos explicó la lección.

¿Os trajeron regalos? (Spain)

Les escribo una carta a mis padres.
I write a letter to my parents. (to them)
LE/LES → SE when combined with a Direct Pronoun
When le/les combine with a direct pronoun (lo/la/los/las), they change to se to avoid "le lo". Easiest way: learn the combos as vocabulary: ME LO (it to me), TE LO (it to you), SE LO (it to him/her/them/you formal/you all), NOS LO (it to us), OS LO (it to you guys, Spain).
When combining indirect and direct pronouns, remember RID order: Reflexive → Indirect → Direct. The indirect pronoun always comes first, then the direct pronoun. Le/Les become SE before lo/la/los/las.
Me lo dieron ayer.
They gave it to me yesterday.
¿El regalo? Te lo envío mañana.
The gift? I'll send it to you tomorrow.
Se lo expliqué a María. (le → se)

¿Las cartas? Nos las enviaron por correo.
The letters? They sent them to us by mail.
¿Os lo contaron? (Spain)

El libro: voy a dárselo / estoy dándoselo / daselo.
The book: I'm going to give it to him/her / I'm giving it to him/her / give it to him/her.
Common Double Pronoun Combinations

Me lavo (la cara).
I wash (my face).
Like indirect objects: the thing said/given returns to the subject.

Some verbs change meaning when reflexive.
