'Hinstellen' (to put down/to stand/to portray) is a separable verb. The prefix 'hin-' goes at the end in a main clause. In subordinate clauses and in the infinitive, the verb stays together.
Er stellt die Bücher ins Regal hin.
He puts the books down on the shelf.
The prefix 'hin-' expresses movement toward a specific place. It emphasizes the direction and destination of the action of placing something.
Kannst du die Stühle bitte dort an die Wand hinstellen?
Could you please put the chairs over there against the wall?
The three meanings can be distinguished well grammatically. The reflexive form 'sich hinstellen' means that a person positions themselves. The construction with 'als' means 'to portray as'. Without these two elements, it is usually about placing an object somewhere.
Stell den Koffer einfach hier hin.
Just put the suitcase down here.
In the figurative meaning, the preposition 'als' always follows. The structure is: 'jemanden/etwas hinstellen als ...' (to portray someone/something as ...). What follows 'als' describes the type of portrayal.
Er versucht, das Problem als unwichtig hinzustellen.
He is trying to portray the problem as unimportant.

'stellen' and 'hinstellen' can both mean that you bring something to a place and put it in an upright position. In many everyday sentences, they are very similar. 'stellen' is more general and fits especially well when the place or arrangement is important. 'hinstellen' puts more emphasis on the movement to a specific spot: something is put down there. Learners can easily confuse the words because both are often used with things like bottles, bags, or chairs. In simple situations, both are usually understandable.

Stell die Tasche bitte neben die Tür hin, dann vergessen wir sie nicht.
Please put the bag next to the door so we don't forget it.
