At the most neutral, it's pure friendship. But if you want more, you can see their dialogue towards you as being romantic or not.
Same with Lana towards the male and Ilima towards the female.
And yes, I'm excluding same-gendered relationships since GF explicitly stated that if you were to have romantic interest in Pokemon, they would be of the MC's opposite gender, going by BW, B2W2, ORAS, and the Shauna interview from XY.
