Only just. Magistral Small 24B fits on the NVIDIA RTX 4080 Super at Q3_K_M, which costs noticeable quality. Expect about 38 tokens/second. A card with more memory is a better experience.

Run it with Ollama

Ollama's default magistral:24b download is Q4_K_M, which needs about 16.2 GB, more than the 16 GB available. Download the Q3_K_M GGUF instead (LM Studio lists quants per model), or try a smaller context length.
