We derive accretion flow properties of the transient black hole candidate(BHC) MAXI~J1543-564 using the RXTE data. We use Two-Component Advective Flow(TCAF) solution to fit the data of the very initial rising phase of outburst(from 2011 May 10 to 2011 May 15). $2.5-25$~keV spectra are fitted using theTCAF solution {\it fits} file as a local additive table model in XSPEC. Weextract physical flow parameters such as the two component (Keplerian disk andsub-Keplerian halo) accretion rates and size and the property of the Comptoncloud (post shock region close to a black hole). Similar to other classicaltransient BHCs, monotonic evolution of low frequency quasi-periodicoscillations (QPOs) are observed during the rising phase of the outburst, whichis fitted with the propagating oscillatory shock (POS) model which describeshow the Compton cloud properties change from day to day. From the nature ofvariations of TCAF model fitted physical flow parameters and QPOs, we onlyfound hard-intermediate and soft-intermediate spectral states during this phaseof the outburst under study. We also calculate frequency of the dominating QPOsfrom the TCAF model fitted shock parameters, and found that they roughly matchwith the observed and POS model fitted values. From our spectro-temporal studyof the source with TCAF and POS models, the most probable mass of the BHC isfound to be $12.6-14.0$~$M_\odot$, or $13^{+1.0}_{-0.4}~M_\odot$.
